Uzbekistan hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

(Uzbekistan supporting cylinder,produced by Hebei Hengyu company）

supporting cylinder are widely used in Uzbekistan，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed supporting cylinder for customers from Uzbekistan.

Introduction to supporting cylinder:

The coordination of the sliding parts of the supporting cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Under normal circumstances, the supporting cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the supporting cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the supporting cylinder and the end cover, the piston and the piston rod, the piston and the supporting cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the supporting cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Factors that should be considered when selecting the oil seal in the supporting cylinder: some specific factors should be taken into account when selecting the oil seal in the supporting cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: supporting cylinder diameter, piston rod diameter, piston rod and piston groove size, supporting cylinder working pressure, supporting cylinder movement speed, hydraulic system oil temperature and supporting cylinder working environment.

When using the supporting cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the supporting cylinder block. If the supporting cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the supporting cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the supporting cylinder, so that the working efficiency of the supporting cylinder is reduced.

Answers to some questions about supporting cylinder:

What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.
